Application filed June 12,1905. Serial No. 264,891.

To all whom it may concern.-

Be it known that I, TIMOTHY STnBBINs, a citizen of the United States, and a resident of Davenport, in the county of Scott and State of Iowa, have invented certain new and useful Improvements in Automatic Windmill-Pull-Out Mechanism for Pumps, of which the following is a full, clear, and exact description, reference beinghad to the accompanying drawings and the letters of reference marked thereon.

My invention relates to pumps, and particularly to the regulating mechanism thereof, which is connected to the pull-out device of a windmill and is designed to prevent the operation of the mill when the ordinary channels for the escape of the water, either the pump or its connections, have been cut 0 The objects of my invention are, first, to provide an automatic pull-out mechanism for the windmill, the parts of which are so constructed and can be so adjusted as to permit the application thereof to any forcepump; second, to permit of the limited involuntary operation of the windmill and pump when the former is subjected to sudden gusts of wind and change of air-currents or is otherwise accidentally rendered free to revolve, to an extent, just sufficient to pull said mill out of tIlG'WlHd, and which efl ectually prevents any abnormal increase of waterpressure in the pump when the discharge of the water from the pump or its connection is otherwise cut off. This I accomplish by the mechanism hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a perspective view of a double-acting pump, showing my invention applied thereto. Fig. 2 is a vertical side elevation thereof, partly in section, showing a part of the union-coupling and auxiliary cylinder adjacent to the base-flange of the pump-head in such a manner as to illustrate the automatic hydraulic actuating mechanism. Fig. 3 is a sectional view showing in detail the upper portion of the pumpcylinder and auxiliary cylinder. Fig. 4 is a vertical section of the pump-cylinders below the base-plate. v

In the drawings, A represents a tubular standard, which is supported by and arises from a suitable base-plate a, which latter next the base of the standard is provided with a raised dome-shaped portion a, which is provided with a central opening therein. This opening is closed by a suitable removable cap or cover B, which is provided with a suitable central guide-opening for thepistonrod O. The upper end of the standard is provided with a cross-head b of suitable pattern, and the latter is provided with a perforated boss X for the guidance of the-piston-rod O. The piston-rod extends up through this boss and has an open socket c pivoted thereto, into which the lower end of the connectingrod (that is operatively connected to the windmill) is fastened.

The lower end of the piston extends into the upper chamber D and the lower cylinder E of the pump, and these parts are of the usual well-known construction, as also are the plungers connected to said piston-rod and operating within the same. The cylinder and chamber are connected by a unioncoupling (1, which has a lateral discharge-pipe F projecting therefrom and preferably at a point opposite thereto has an L-shaped tubular branch e, into whose upturned outer extremity a nipple (whose upper end is expanded or flanged) is screwed or otherwise fitted, which nipple is screwed into the lower end of and supports the auxiliary cylinder G. The upper end of this auxiliary cylinder extends into or is in alinement with a suitable opening m in the base-plate a, and thisopening is closed by a loose cover G, placed over the same, which has a central guide-aperture through which the plunger-rod H extends. The plunger-rod is provided with a suitable imperforate head you its lower end within the cylinder G, and when this head is at the limit of its upward stroke it passes beyond a series of perforations h, arranged circumferentially in its upper end just below the base-plate.

The upper ortion of the lunger-rod H ex tends vertica ly up throug the guide-aperture of a' boss made integral with cross-head b and has its up er end pivotally connected to one end of a s eev'e'I, through which a lever J extends and is when properly adjusted secured therein by a set-screw The other end of sleeve I is pivotally secured to the upper end of a vertically-disposed link K, whose ower end is pivoted to and supported by the end of the cross-head l) opposite the plungerrod and serves as a movable fulcrum for the lever J, which latter is, as shown, provided with an adjustable weight k on the end portion nearest the plunger-rod and is pivotally connected at the opposite end to the pull-out rod of a windmill.

If desired, the discharge-pipe may lead to a tank or other receptacle for water and have a float-valve of any well-known construction connected to its discharge end.

So provided, the operation of my invention is as follows: Suppose the mill to be pulled out of the wind and the two-way valve or the float-valve be moved into such position as to close the discharge-pipe. The position of the plunger-head would be near the top of the auxiliary cylinder. Now should a sudden gust of wind or a change of direction of the wind cause the windmill to operate the pump the water being shut off from all other exits will rise in said cylinder G until it reaches the series of perforations h and then discharge therefrom without affecting the plunger and piston and weighted lever connected therewith or the pull-out mechanism, to which the latter is connected. Should the windmill accidentally get into the wind by reason of the sail or steering-vane accidentally coming in line with the direction of the wind and the plunger be thereby moved down into the cylinder G to a point below the perforations it, the water when the pump begins ot operate will rise in said cylinder and force the plunger and piston-rod upward uiitil said openings h are uncovered and will then' flow through said openings out of the cylinder. As the piston-rod thus moves upward it actuates the weighted lever and causes it to operate the pull-out mechanism, so as to move the steering-vane of the windmill out of the wind or parallel with said mill again.

It is apparent that my improved automatic regulation can be applied to any two-pipe double-acting or to a single-acting forcepump and that its use avoids the necessity of making a specially-constructed pump with an inseparable regulator attachment for this purpose. One of the most important features of my invention is that when it is desired to repair the plungers or foot-valve or the piston-head in the auxiliary cylinder all that is necessary is to remove or raise the cover B and the cover G, and the parts referred to can be lifted out without necessitating getting down into the pit or removing the platform.
